Abstract: Systems and methods for detecting and/or mitigating video artifacts in a video. A processor in a computing device may be configured to receive the video from a video source (e.g., codec or from any other video source compressed or uncompressed) subtract pixel intensities from two consecutive frames in the video to generate a residual, analyze the residual to detect small rectangular shapes, and identifying a video artifact in the video based on a result of the analysis.

Abstract: Various embodiments include systems and methods for performing mid-stream content delivery network (CDN) steering. A processing system in a manifest manipulator may receive a content request from a client device that is directed to obtain content from a uniform resource locator (URL) associated with a primary on-premise CDN. The processing system may also receive an event notification from a CDN decision server that indicates that there is an issue with the primary on-premise CDN. The processing system may modify a manifest file associated with the received content request in response to receiving the event notification from the CDN decision server, and send the modified manifest file to the client device to cause the client device to obtain the requested content from a third-party CDN.
